MS4043 Cylinder Guard

MS4043 Cylinder Guard is a hardened-steel ring to protect cylinder from vandalism.

Function:

The standard mortise cylinder is made of brass. It is literally a soft spot in narrow stile door security. Using special pliers, a pipe wrench or other leverage device, a burglar can tear the cylinder out of the door, leaving an opening through which the deadlock may be operated. The MS4043 Cylinder Guard offers a three-way defense against this problem:1. The outer shield ring is fully beveled to offer poor purchase for either prying or twisting.2. The ring is hardened steel so that the combination of shape and hardness make it virtually impossible to grip, even with sharpened tools.3. In the event that a prying tool such as a cold chisel is driven into the stile behind the shield ring, the would-be burglar is obliged to pull a heavy steel plate through a round hole in the 1/8" metal door stile. This degree of leverage is far beyond that available with most hand tools.

Features:

Security Ring: Made of hardened-steel. Free swiveling when properly installed.
